Photo display frame and attachment means therefor

ABSTRACT

A display frame for temporarily exhibiting photographic prints and similar planar display material by magnetic attachment. The frame includes a planar backing member of metallic material, and the display material is affixed thereto by means of spots of planar synthetic resinous material having magnetized metallic particles therein which are magnetically attracted to the backing member, and are temporarily affixed to a rear surface of the print or display material by a coated adhesive substance having relatively limited adhesive properties relative to hard calendered paper, so as to be readily peelable therefrom for reuse with other display material.

BRIEF DESCRIPTION oF- Tl-lEPRIOR ART It is known in the prior art toaffix photographic prints and similar material to a backing board fordisplay using adhesive tape, mounting corners, clips, pins, tacks andthe like. It is also known to employ a plurality of small bar magnets tohold the material to be dis- I played against a magnetically attractivesurface, to permit ready removability. Such bar magnets are, however,exposed to view, and tend to degrade an otherwise attractive display.

BRIEF DESCRIPTION OF THE PRESENT INVENTION Briefly stated, the inventionconetemplates the provision of a" display-frame defining a displayopening, and mounting a backing boardof planar metallic material. Thedisplay material is magnetically affixed to the backing board byproviding a series of mounting means comprising small pieces of a planarsynthetic resinous material having magnetized particles imbeddedtherein. One surface of :this material is placed in juxtaposed positionwith respect to the backing board. The other surface is permanentlyadhered to a correspondingly shaped piece of tape or filament having anadhesive coating on each side thereof, one coating layer having strongeradhesive properties than the other, and being permanently adhered to onesurface of the synthetic'resinous material. The other adhesive surfacehaving lesser adhesive properties is selectively adhered to the rearsurface of the photographic print which is normally of hardcalenderedpaper, so as to be readily removable therefrom, withoutdisturbing the adhesive attachment of the tape orfilament to thesynthetic resinous material. The attaching means may thus be used manytimes, until the ability of the adhesive to adhere to the rear of aphotographic print is lost.

BRIEF DESCRIPTION or THE DRAWING In the drawing, to whichreference willbe made in the specification, similar reference characters have beenemployed to designate corresponding parts thoughout the several views.

FIG. 1 is a front elevational view of an embodiment of the invention.-

FIG; 2 is a longitudinal sectional view as seen'from the plane 2-2 inFIG. 1.

FIG. 3 is a fragmentary enlarged sectional view as seen from the plane3-3 in FIG. 2.

DETAILED DESCRIPTION OF THE DISCLOSED EMBODIMENT In accordance with theinvention, the device, generally indicated by reference character 10,comprises broadly a frame element 11 and aplurality of individualattaching means 12 for supporting one or more prints or other displaymaterial 13 of well known type.

The frame element 11 may be of any desired construction, as for example,to include a peripheral wood frame 14 having side members 15 and 16, andend members 17 and 18 defining an opening 19 therebetween. A rearsurface 20 defines a continuous rabbet 21 seating a backing member 22including a metallic plate 23 having an optional fabric or felt covering24 upon the exposed surfaces thereof.-

The attaching means 12 are generally similar, and accordingly, adescription of one such means will serve to describe all. Each meansincludes a body 26 of flexible planar synthetic resinous material, suchas polyethylene or the like, in which there have been imbedded particlescapable of retaining a magnetic charge. Materials of this type are knownin the art, and are presently commercially available from MinnesotaMining and Manufacturing Company (3M) of St. Paul, Minn. This materialis cut into circular or other suitably shaped spots or pieces after oneplanar surface of the same has been suitably adhesively coated. Thus,each means includes an uncoated surface 27 adapted to be placed injuxtaposition to the backing member 22, and a second surface 28 to whichadhesive is applied, both surfaces being bounded by a peripheral edge29.

Since the affinity for most adhesives for hard coated paper normallyfound asa rearward surface of a photographic print, and the surface ofthe synthetic resinous material, it is necessary that steps be taken toassure that when an attempt is made to peel the means 12 from thesurface of the print, the adhesive will remain attached to the means 12.As seen in FIG. 3, this is most conveniently accomplished by providing adouble sided tape or filament 30 having a first adhesive 31 applied toone surface of a base 32, and a second adhesive 33 applied to theopposite surface. The first adhesive is of greater strength per unitarea, and is more or less permanently affixed to the surface 28, whilethe second adhesive 33 is employed to interconnect the rear surface ofthe print or display material 13. Both of the adhesives 31 and 33 may bewell known rubber base types, with the former more thickly applied, thatis to say with a lesser degree of evaporable vehicle, so that itsbonding strength is inherently greater. The tape 30 is preferablyapplied to one surface of the body 26 prior to the cutting of the samefrom a larger web, to simplify manufacturing procedures.

In use, it is necessary only to affix one or more of the means 12 to therear surface of a desired print 13 and place the print upon the forwardsurface of the backing member 22 to enable magnetic attraction betweenthe means and the board to occur. The print may be left in position aslong as desired, and when replacement with another print is made, it isnecessary only to remove the print with the attached means 12, and peelthe same from the rear surface of the print. Since the adhesive face ofthe print, it peels relatively easily, and until detached fibers I fromthe paper stock comprising the print, or other soil become imbedded inthe adhesive surface, it may be used many times without difficulty.Since the adhesive layer 31 is considerably stronger, the adhesive willalways remain attached to the body 26 rather than the print, and onlyreasonable care need by exercised in the detaching operation.

I wish it to be understood that I do not consider the invention limitedto the precise details of structure shown and set forth in thisspecification, for obvious modifications will occur to those skilled inthe art to which the invention pertains.
